Csharp调用微软COM转换ppt为HTML

使用微软的office中的ppt软件只要使用另存为就可以把一个ppt保存为HTML网页文件。但如何通过程序调用完成转化呢？

以下使用office 2007为例，其他版本略有不同。 1添加引用，对于不同的版本，有所不一样。当然前提自然是安装了对应的微软office软件。



2转换代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using PPT = Microsoft.Office.Interop.PowerPoint;
using Microsoft.Office.Core;
namespace CommonConvert
{
public class PPTToHtml
{
/// <summary>
/// 使用反射调用方法,返回生成的HTML文件路径
/// </summary>
/// <param name="pptFullFileName"></param>
/// <returns></returns>
public string PptToHtmlFile(object pptFullFileName)
{
//在此处放置用户代码以初始化页面
PPT.Application ppt = new PPT.Application();
Type wordType = ppt.GetType();
PPT.Presentations docs = ppt.Presentations;
//打开文件
Type docsType = docs.GetType();
PPT.Presentation doc = (PPT.Presentation)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { pptFullFileName, false,false,false });
// PPT.Presentation doc = (PPT.Presentation)docsType.InvokeMember("Open", System.Reflection.BindingFlags.InvokeMethod, null, docs, new Object[] { pptFullFileName});//后三个参数不设置，会出现错误Presentations.Open : Invalid request. The PowerPoint Frame window does not exist.
Type docType = doc.GetType();
string htmlFullFileName = pptFullFileName + ".html"; //HTML文件路径
object ofmt = PPT.PpSaveAsFileType.ppSaveAsHTML;
//转换格式，另存为
docType.InvokeMember("SaveAs", System.Reflection.BindingFlags.InvokeMethod, null, doc, new object[] { htmlFullFileName, ofmt });
docType.InvokeMember("Close", System.Reflection.BindingFlags.InvokeMethod, null, doc, null);
//退出
wordType.InvokeMember("Quit", System.Reflection.BindingFlags.InvokeMethod, null, ppt, null);
return htmlFullFileName;
}
/// <summary>
/// 直接调用方法，不使用反射
/// </summary>
/// <param name="pptFullFileName"></param>
/// <returns></returns>
public string PptToHtmlFile2(string pptFullFileName)
{
//在此处放置用户代码以初始化页面
PPT.Application ppt = new PPT.Application();
PPT.Presentations docs = ppt.Presentations;
//打开文件
PPT.Presentation doc = docs.Open(pptFullFileName, MsoTriState.msoFalse, MsoTriState.msoFalse, MsoTriState.msoFalse);
// PPT.Presentation doc = docs.Open(pptFullFileName); //后三个参数不设置，会出现错误Presentations.Open : Invalid request. The PowerPoint Frame window does not exist.

string htmlFullFileName = pptFullFileName + ".html"; //HTML文件路径
//转换格式，另存为
doc.SaveAs(htmlFullFileName, PPT.PpSaveAsFileType.ppSaveAsHTML);
doc.Close();
//退出
ppt.Quit();
return htmlFullFileName;
}
}
}
